  • Laser decontamination method
    Patent number: 6056827
    Abstract: A laser decontamination method includes the steps of incorporation of a condenser lens in a gas supply nozzle, supplying a gas toward a contaminated member while moving the gas supply nozzle relatively to and along a surface of the contaminated member with a laser beam which is condensed by the condenser lens applied thereto, and thereby continuously melting or evaporating a contaminated surface layer so as to remove the same to clean the contaminated member. The gas is supplied asymmetrically with respect to the axis of the laser beam.
